Key Largo Bridge Run

Key Largo Bridge Run takes place in Key Largo, in Monroe County, Florida, on December 5, 2026, over a single 5K. The course crosses one of the area's landmark bridges, which opens up a clear view over the ocean, and you cover it to the sound of the waves and in the sea breeze that defines the Keys.

A bridge is about the only vertical gain you will find in this part of Florida, so expect a gentle climb and descent rather than a completely flat 5K, and hold something back on the way up. The distance itself suits everyone: newcomers can walk sections without losing the experience, while regular runners can use it as a short, hard effort inside a winter block. Three easy runs a week for a month, plus a few short pickups in the final two weeks, is enough to race it rather than simply finish it.
